php - 测试 Laravel Controller 时 View 中的 undefined variable

Question

我正在尝试使用 PHPUnit 在 Laravel 4 中的 Controller 上测试一些操作。

public function testAboutPage()
{
    $this->client->request('GET', 'about');

    $this->assertResponseOk();
}

此外，我在 App::before() 过滤器中将一个变量绑定(bind)到我的 View 。

App::before(function($request)
{
    View::share('usersCount', User::remember(60)->count());
}

这是我的 Controller :

class PagesController extends BaseController
{
    public function about()
    {
        return View::make('pages.about')->withTitle("About");
    }
}

但是，在测试中 undefined variable 之前，我的测试失败了。这是 PHPUnit 的失败输出。

12) PagesControllerTest::testAboutPage
ErrorException: Undefined variable: usersCount (View: app/views/layouts/application.blade.php) (View: app/views/layouts/application.blade.php)

我该怎么做才能解决这个问题？在浏览器或生产环境中查看时，该变量没有问题。

从文档中可以看出过滤器被禁用了。我认为这只是指在路由文件中定义的过滤器，但它也会影响应用程序之前/之后的过滤器。

Note: Route filters are disabled when in the testing environment. To enable them, add Route::enableFilters() to your test.

我已将此添加到我的测试中，使它们变绿。

public function setUp()
{
    parent::setUp();

    Route::enableFilters();
}
